Question : Microsoft Exchange Service Host Fails to start

I have 2 Exhcange servers 2007 server running in Coexistance with an Exchange 2003 Environment. Server 1 (2007) will not start the "Microsoft Exchange Service Host" Service Even after a manually trying to start it will error out saying "Error 1053: The service did not respond to the start or control request in a timely fashion".  I get two events in the log that are as follow:

Event Type:      Error
Event Source:      Service Control Manager
Event Category:      None
Event ID:      7000
Computer:      EXCH01
Description:
The Microsoft Exchange Service Host service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion.

And

Event Type:      Error
Event Source:      Service Control Manager
Event Category:      None
Event ID:      7009
Date:            4/16/2008
Time:            4:05:06 PM
User:            N/A
Computer:      EXCH01

Server 2 (Also 2007) on the other hand all services star with no problems.

Neither of the 2007 servers have SP1 installed and both are on Windows 2003 Server R2.

Please help I am banging my head against a wall with this.

Answer : Microsoft Exchange Service Host Fails to start

Did you follow this?


Method 1: Configure User Rights
NOTE: This method is for Windows XP Professional only, not for Windows XP Home Edition.

If the right to log on as a service is revoked for the specified user account, restore the right by using either of the following methods, as appropriate to your situation.
On a Domain Controller
If the user is in an Active Directory domain, follow these steps:
1.      Log on to the domain controller as administrator.
2.      Start the Active Directory Users and Computers snap-in.
3.      Right-click the organizational unit (OU) in which the user right to log on as a service is granted, and then click Properties.

By default, this is in the Domain Controllers OU.
4.      Click the Group Policy tab.
5.      Click Default Domain Controllers Policy, and then click Edit.
6.      Expand Computer Configuration, expand Windows Settings, and then expand Security Settings.
7.      Expand Local Policies, and then click User Rights Assignment.
8.      In the right pane, right-click Log on as a service, and then click Security.
9.      Add the user that you want to the policy, and then click OK.
10.      Quit the Group Policy Editor, click OK, and then close the Active Directory Users and Computers snap-in.
On a Local Computer
If the user is on a stand-alone Windows XP-based computer, follow these steps:
1.      Log on to the computer as administrator or as a member of the Administrators group.
2.      Start the Local Computer Policy snap-in.
3.      Expand Local Computer Policy, expand Computer Configuration, expand Windows Settings, and then expand Security Settings.
4.      Expand Local Policies, and then click User Rights Assignment.
5.      In the right pane, right-click Log on as a service, and then click Properties.
6.      Click Add User or Group, add the user that you want to the policy, and then click OK twice.
7.      Close the Local Computer Policy snap-in.

Method 2: Configure Logon Information for the Service
If the password is changed on the user account that the service uses to log on, configure the password to match the current password for that user. To do this, follow these steps:
1.      Click Start, click Control Panel, click Performance and Maintenance, and then click Administrative Tools.
2.      Double-click Services.
3.      In the right pane, right-click the appropriate service, and then click Properties.
4.      Click the Log On tab, type the correct password in the Password and Confirm Password boxes, and then click OK.
5.      Right-click the service, and then click Restart.
6.      Quit the Services tool.

Back to the top
Method 3: Configure the Service to Use the Built-in System Account
If the service still does not work with the specified user account, configure the service to log on to the built-in system account. To do this, follow these steps:
1.      Click Start, click Control Panel, click Performance and Maintenance, and then click Administrative Tools.
2.      Double-click Services.
3.      In the right pane, right-click the appropriate service, and then click Properties.
4.      Click the Log On tab, click Local System account, and then click OK.

NOTE: In most situations, it is not necessary to configure a service to interact with the desktop. You do not need to select the Allow service to interact with desktop check box.
5.      Right-click the service, and then click Restart.
6.      Quit the Services tool.
When you attempt to open the properties of a service by using the Services tool in Control Panel, the computer may stop responding (hang) and/or you may receive the following error message:
The RPC Server is unavailable.
You may receive this error message if the remote procedure call (RPC) service is not started because of a logon failure with that service or a dependency service. Some services have dependency services, and these services do not start until their dependency services start first (for example, the Workstation service).

If you cannot start the Services tool, use Registry Editor to configure the service to use the built-in system account. To do this, follow these steps:
1.      Click Start, and then click Run.Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 (http://support.microsoft.com/kb/322756/) How to back up and restore the registry in Windows

2.      In the Open box, type regedt32, and then click OK.
3.      Locate the following registry key, where ServiceName is the service that you want to configure:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ServiceName
4.      In the right pane, double-click ObjectName.
5.      In the Edit String dialog box that appears, type localsystem, and then click OK.
6.      On the File menu, click Exit to quit Registry Editor.
7.      Click Start, click Control Panel, click Performance and Maintenance, and then click Administrative Tools.
8.      Double-click Services.
9.      Right-click the service, and then click Restart.

You may need to restart the computer for some services to restart properly.
